HPR-02.

Self-regulating pumps for open circuit operation.

Design characteristics Controller types

— axial piston pump in swashplate design for high pressure — LP load sensing with pressure cut-off
open circuit systems — H1L load sensing with hydraulic ∆pLS – override
— clockwise or counter clockwise rotation — E1L load sensing with electrical ∆pLS – override
— self-priming at high nominal speed — LEP load sensing with electric stroke limiter
— tank pressurization or swash angle reduction for and pressure cut-off
high speed applications — ETP electro-proportional with hyperbolic power-
— adaptive noise optimization SPU limiter and pressure cut-off
— decompression fluid is discharged via pump housing to — TL2 load sensing with hyperbolic power limiter
keep suction side calm
— exact and robust load sensing controllers with Product advantages
or without swash plate position feedback
— optimum interaction with Linde LSC control valves
and LinTronic
— energy saving operation by ‘flow on demand’-control
— dynamic response
— excellent suction up to rated speed
— noise optimization over the whole range of operation
— compact design
— high power density
— high reliability
— long working life
